Warning
1. Do not use for purposes other than those defined for the products by series. Please inquire about use of products for other than their specified purposes.
Warning
1. Tighten the partition nuts for partition unions (PM), partition unions P (PMP) and partition union elbows (PML) to within the specified tightening torque range.

2. Tightening partition nuts may cause deformation to the object being tightened or cause oil to adhere to its surface, which in turn will loosen the partition fixing area.
3. Our air pressure pipe coupling anticipates that tubes installed before use, and thus if air is applied when tubes are not attached to flashings, etc., the elastic sleeves may be ejected outside of the product body.
Please refer to the manufacturer's catalog for safety precautions other than those listed above.
